Batman; how not to let down a superhero

Passive-aggressive avoidance--man, I could write a book of vignettes on how to pull this off with panache. Batman, who no doubt suspects me of being one of those girls who play games, called me several times trying to find out if I was up to hanging out with him decked out in his Batman inspired regalia. I couldn't simply pick up the phone and say no, I had to wait for him to leave increasingly annoyed messages, and waited until the next to last minute to call and give my regrets, getting quickly off the phone to take a fake nap. I'm hoping he'll be done with me now, disgusted and annoyed so that I don't have the untidy task of avoiding him or worse yet, telling him I'm not interested. I suspect we have not heard the last from Batman, but a girl can hope.
